Comment (by pramsey):

 Have a look at OverlayNG.setStrictMode(). If you turn on strict mode, the
 results of overlays will only include components of a single
 dimensionality. Unfortunately (?) the results of the standard methods on
 Geometry have to match up to the old behaviour for legacy reasons, so
 strict mode is turned off by default.
